ILLUMINATING APPLIANCE Application filed February 20, 1922. Serial No. 537,845.

To allwhom it may concern Be it known that I, WILLIAM A. INGLER, a citizen of the United States, and a resident of Newark, in the county of Licking and State of Ohio, have invented certain new and useful Improvements in Illuminating Appliances, of which the following is a specification.

The object of this invention is to provide a lower closure for bowls, reflectors or the like used with lighting fixtures so that such units may be used in their original form as open-mouthed units, or else as closed units to conform to other conditions.

Fi 1 is a vertical cross section of a lobe showing the closure member inserted alfway therein and illustrative of the method in which such member is introduced.

Fig. 2 is a bottom plan view of an openmouthed globe with the closure member in final position.

Fig. 3 is a fragmentary vertical ,cross section on line 3-3 of Fig. 2 at a point of contact where the closure memberis fur- 2 nished with a rim.

Fig. 4 is a fragmentary cross section of the wall of the globe of the closure member on line 4.4 of Fig. 2 at the points where the rim of the closure member has been 80 taken away.

has beenfound that the use of a'lighting unit having a closed bottom is most desirable. My device permits the closing of 85 open-mouthed globes, reflectors or other envelopes now in use or ermits the marketing of open-mouthed env pes to be used with or without the bottom closure so that light -can be directly emitted through the open 40 mouth of the enclosure or else it can sealed in the manner hereinafter explained. In the figures 1 is a globe used in connection with lighting fixtures having a hollow portion 2 and walls 3. This type of envelope has been arbitrarily chosen as the invention can be used with any type of bowl or reflector where the lower or mouth opening has been left open. .Such bowls or reflectors must have a reentrant' edge at the lower opening on which the closure member can rest. The invention consists in provid ing such opening 4 with a closure cap or that the mouth or rim of made narrower than the maximum member 5, distinguished by having a rim 6 which does not extend all the way around the cap but at points 7 and 7 opposite each other, the rim is omitted so that the closure can be introduced into the opening at the points where the rim is omitted and when the cap is so introduced it can be turned so the globe 1 furnishes a secure seat or hold for the rim 6 of the cap. An ornamental tip 9 is here shown as placed on the cap, but this is not an essential part of my invention. The cap is easily removed by tipping it upwardly inside of the globe until the straight sides 7 and 7' come in contact with the mouth of the globe when the cap easily slides out in the position shown in Fig. 1; In the ordinary globe or reflector with sealed bottom, the entire closure must be removed to clean or take out the lamp, and the upper opening of such enclosure must be large enough to clear the greatest diameter of the lamp. A feature of the present invention is the fact that it is only necessary to remove the lower cap to take out the lamp, if the opening 4 in the globe be large enough, and it is assumed that when the unit is sold as a complete new product this will always be the case. It will 'be readily seen in such case'that the upper opening shown at 2 in Fig. 1 mziy be amp diameter if so desired, because the lamp is removed by way of the lower opening.

The cap can be made of transparent or light difl'using glass or it may be made of. metal and be absolutely opaque. The construction' andv princi le is not affected by the materialused eit er in the envelope itself or in the cap.

.I claim:

A globe or reflector comprising an enve lope having a lower 0 ening, and a separate closure member with its perimeter partially curved and partially straight, the straight sides of the closure being adapted to enter the lower opening at an angle thereto, so as to permit the closure after complete entry to rest in the interior of the lower opening of the envelope to. completely close the same.

Signed at Newark, in the county ofv Licking and State of Ohio,this, 13th day of February, 1922.
